Abstract: METHOD AND APPARATUS FOR EXTENDING A BOOM ASSEMBLY           Abstract of the Disclosure:   The overall length of boom assembly can be increased by the use of a pair of boom extension sections.          When the boom extension sections are not required, they are sup-ported at storage locations adjacent to one side of a main boom assembly.  When the overall length of the main boom assembly is to be increased, a First one of the boom extension sections is pivotally connected with the outer end portion of the main boom assembly and the second boom extension section is pivotally con-nected with the outer end portion of the first boom extension section.  The two boom extension sections are swung outwardly together around the outer end of the main boom assembly.  After the first boom extension section has been firmly connected with the outer end portion of the main boom assembly, the second boom extension section is pivoted about the outer end portion of the first boom extension section.  A gantry frame is then erected to hold the two boom extension sections against movement relative to each other so that the two boom extension sections form a rigid structure which increases the overall effective length of the boom assembly.  In order to guide movement of the second boom extension section from its storage position into engagement with the first boom extension section, a roller on the second boom extension section rolls along a track which is connected with the main boom assembly.  As the second boom extension section is moved into engagement with the first boom extension section, the roller moves off the track to thereby release the second boom extension section for movement away from the main boom assembly.

Abstract: Abstract of the Disclosure Incorporating 500 to 5,000, preferably 2,000 to 4,000 parts per million of Fischer-Tropsch wax of high congealing point into beads of expandable polystyrene made by suspension polymerization yields greater advantages, and conditions (time, temperatures, and recipe) of the polymeri-zation become less critical.  The drying or conditioning ster before the pre-expansion under particular conditions to generate a suitable cell structure need not be followed, and a step of coating with zinc stearate or the like before the pre-expansion may be omitted.  Unexpanded beads are obtained which yield consistent cell structure, independent of conditions of their storage.  Beads of higher pentane content can be used, and final articles of lower density may be obtained.  The throughput of the pre-expander may be increased, and the beads, after pre-expansion, have good free-flowing (reduced clumping) and mold-filling characteris-tics.  Other things being equal, they can be molded with a shorter cycle time, yet exhibit excellent fusion and other desirable characteristics.

Abstract: LEAK FREE HOUSING FOR VERTICAL SCREW CONVEYOR            Abstract of Disclosure A vertical joint structure is shown extending longi-tudinally of a generally cylindrical housing encasing a screw conveyor for a breading machine or the like.  The housing com-prises two generally C-shape half portions formed of sheet metal and assembled by means of a novel joint structure along two longitudinal zones diametrically opposite in the housing.          One half portion is fixed in the machine and the other half portion is movable toward and away from a tight fit of the joint structure with the fixed half portion.  The distal edges of the movable C-shape half portion extend  a short distance beyond a diameter of the housing at approximately a right angle to that diameter and are there bent downwardly and outwardly at an acute angle to a zone just at, or a little beyond, that diameter and there bent outwardly approximately radially of the cylindrical housing.  This forms a first linear sealing surface at the acute angle portion.  The distal edges of the fixed C-shape half portion approach the first linear sealing surface outside thereof and parallel to the same acute angle to a zone close to the first mentioned zone and are there bent outwardly parallel to the previously mentioned radially extending portions of the movable half portions.  This forms a second linear seal-ing surface parallel to the first linear sealing surface.  An arrangement is provided to clamp the two sealing surfaces tightly together.

Abstract: ABSTRACT       A solar energy system for transmitting solar energy from space to an earth location and putting it to useful work either as heat or light energy, or by convert-ing it into some other form of energy such as steam or electrical power.  A receiver satellite is in polar orbit and a relay satellite is in equatorial orbit, rotating with the earth and therefore stationary with respect to earth location.  Solar energy is collected by the receiver satellite through an array of paraboloid collectors and focused by a series of mirrors onto a coherent radiation energy generator, preferably a laser beam generator.  The laser beam is directed by an output mirror to another output mirror on the relay satellite which redirects it to a selected earth location.  Alternatively, the relay satellite may convert the laser beam to a maser beam to better penetrate clouds, smoke and haze at the earth location.  The outlet mirrors on the two satellites are mounted on gimbals and are power-operated under continuous automatic telemetry control between the satellites and the ground to direct the laser or maser beam to the earth location.  Provision is made on one of the satellites for modifying the beam through a constructive interference filter or a diffuser/expander lens, or both, to regulate the kind of energy and the area covered at the earth location.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a high volume air sampler for sampling particulate matter in an area during a predetermined time period.  It provides a structure hav-ing a vertically movable roof which may be raised to expose a filter paper during a sampling period and thereafter be lowered to seal the filter paper enclosure at the end of the sampling period.  The roof is mounted on drive screws which serve to raise the roof at the start of the sampling period and to lower the roof at the end of the sampling period.  A gear reducer and reversible motor serve to turn the drive screws through a chain and sprockets connected to such drive screws.  A timer initiates the start of the sampling period and starts the reducer and motor which in turn through the drive screws, chain and sprocket assembly raises the roof of the high volume sampler.  When the roof reaches its uppermost position a limit switch turns on a vacuum fan motor which thereby causes particulate to collect on the filter paper.  At the end of the pre-set period the gear reducer and motor lower the roof, a second limit switch shuts off the vacuum fan motor,  and the roof isolates the filter paper from further particulate fallout.

Abstract: ABSTRACT OF THE DISCLOSURE         The improved method of the present invention comprises charging a vented alkaline electrolyte-containing electro-chemical cell employing an electrode pair selected from the group consisting of nickel-zinc, nickel-cadmium, silver-zinc and silver-cadmium and at least period measuring the charging efficiency of the cell by determining the rate of gas evolution from the cell.  The charging of the cell is terminated when the charging efficiency substantially decreases, signifying the cell having reached an about full charge.  The charging efficiency at that point normally substantially decreases to a value of about 0.5 ? 0.2.  In the alkaline electrolyte-containing cells, the charging efficiency is determined according to the formula   wherein E is the charging efficiency, I is the current in amperes and ? is the gas generation rate in the cell in cc per second.  The improved method prevents overcharging of the cell and accurately determines when an about full charge is reached.  Accordingly, charging can be carried out without risk of damage to the cell and with the greatest efficiency.

Abstract: ABSTRACT            A clamping device for clamping a structure, such as a door or window case, into a frame of substantially U-shape cross-section and which has an inner web wall with an offset portion and a sidewall on each side, comprises, a clamping body of substantially U-shape cross-section.  The clamping body has a back web wall adapted to be secured to the structure and a leg wall on each side of the web wall which extends outwardly therefrom.  At least a portion of the length of each of the leg walls is resilient so that it may be bent inwardly or outwardly.  The substant-ially U-shaped abutment has a back abutment wall which is adapted to be slidably engaged into a receiving groove at the offset portion of the frame.          It includes an abutment sidewall on each side which is disposed alongside the respective ones of the leg walls.  A clamp member is movably disposed between the side leg walls of the clamping body and it is displaceable to move these walls into clamping engage-ment with the sidewall of the abutment.  This clamping interengagement is effected by a set screw which is threaded through the offset portion of the frame and through both the side leg walls of the clamping body and the abutment sidewalls and into the clamp member so that rotation of the set screw effects shifting of the clamp member to cause the movement of the side leg walls into engagement with the abutment walls and effect the clamping of the structure in the frame.
